Title: Method for connecting circuit board and electronic circuit device using it
Inventor: YODA TOMOKO
IPC: H05K3/34
Filed: 1995-04-18
Abstract: PURPOSE: To prevent the segregation of Pb on the boundary between an electroless-plated Ni-B metallized pad containing Pb and formed on a circuit board and parts by connecting the parts to the metallized pad by forming an Ni-Sn alloy of an Sn-based brazing material. CONSTITUTION: The surface of a conductor substrate is pretreated by soft etching the surface with an alkaline solution, neutralizing the surface with an acid, and activating the surface with a liquid containing a lead compound after degreasing the surface. Then, after an electroless-plated Ni-B film 5 is formed, an electroless-plated Au film 15 is formed and the film 15 is metallized. After the film 15 is metallized, the adhesion between the joined metallic layers 5 and 15 is improved by mutually diffusing the films 5 and 15 to each other. Then I/O pins 17 mounted with Au-20Sn are positioned on the metallic layers formed in the conductor section of the substrate and the pins 17 are heated. Therefore, the segregation of Pb on the boundary between the pins 17 and metallic layer can be prevented, because the Pb can be diffused in the formed intermetallic compound layer.

Title: Nonwoven fabric interlocked with feather fiber, its production and heat-insulation material and moisture-controlling material produced by using the nonwoven fabric
Inventor: KAWAGUCHI YOSHIHIRO
IPC: D04H1/42
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To obtain a wet-process nonwoven fabric having excellent heat- retaining property and heat-insulation property. SOLUTION: A nonwoven fabric interlocked with feather fiber is produced by ejecting high-pressure water jet against a sheet produced by the wet sheet- making process of feather fiber and a fiber composition such as pulp fiber, thereby entangling the fibers of the fiber composition and the feather fiber. This water-jet entangled nonwoven fabric is suitable for heat-retention use because the feather fiber entangled with the pulp fiber, etc., almost completely holds the characteristic properties of the feather fiber such as heat-retaining property and heat-insulation property. Further, the process has excellent productivity and a wet-process nonwoven fabric can be produced at a low cost by the adoption of the water-jet entangling process.

Abstract: PURPOSE:To accomplish miniaturization of equipment by a method wherein the relative speed of the liquid level against the material to be dried up is set by fixing the material to be dried and lowering the liquid level, and a dust- generating part is eliminated. CONSTITUTION:The carrier 3, in which a wafer 2 is housed, is put in an overflow vessel 1 in the state wherein the overflow vessel 1 is full of water and the supply of water is continued. A water draining valve 9 is opened, and a supply water flow rate control valve 5 and a drain water flow rate control valve 8 are controlled in such a manner that the water level lowering speed becomes slow and also it becomes constant. The surfaces of the wafer 2 and the carrier 3 are dried up before the water level comes down to the point lower than the bottom part of the carrier 3 by the action of surface tension and by natural drying. When the carrier 3 is picked out from the overflow vessel 1, the ultra-pure water remained on the end part of the wafer 2 and on the bottom part of the carrier 3 is removed from the grooves of the wafer receiving part and the carrier receiving part. As a result, the dust-generating part is eliminated, and the miniaturization of the equipment can be accomplished.
